This paper describes Mokken scale analysis as a method for assessing the unidimensionality of a set of items. As a nonparametric stochastic version of Guttman scale analysis, the Mokken model provides a useful starting point in scale construction since it does not impose severe restrictions on the functional form of the item trace lines. It requires only that the item trace lines are monotonically increasing and that they do not cross. After describing the Mokken method, we illustrate it by… 
A FORTRAN 77 program for a nonparametric item response model: The Mokken scale analysis
A nonparametric item response theory model—the Mokken scale analysis (a stochastic elaboration of the deterministic Guttman scale)—and a computer program that performs this analysis are described.
Psychology of Computer Use: VIII. Utilizing a Nonparametric Item Response Model to Develop Unidimensional Scales: Mokscal
MOKSCAL is a program for the Mokken (1971) scale analysis based on a nonparametric item response model that makes no assumptions about the functional form of the item trace lines. The only constraint
SPSS-X Procedure and Standalone Programs for the Mokken Scale Analysis: A Nonparametric Item Response Theory Model
A nonparametric item response theory model, the Mokken scale analysis, and program are described. Three scaling procedures are distinguished: a search procedure, the evaluation of the whole set of
Mokken scale analysis for polychotomous items: theory, a computer program and an empirical application
An extension of Mokken's nonparametric item response models from dichotomous items to items with two or more ordered answer categories is proposed and a computer program to analyze multicategory item scores is presented.
Using Mokken methods to develop robust cross-national scales: American and West German attitudes toward abortion
A fundamental methodological issue in cross-national research on attitudes is the comparability of the attitude measures across populations. We address this issue by presenting the Mokken method and
Abortion Attitudes, 1984-1987-1988: Effects of Item Order and Dimensionality
It was concluded that the six abortion items are unidimensional and, therefore, create a single scale to measure the change in abortion attitudes across the three periods.
An IRT validation of the Affective Self Rating Scale
AS-18 has good basic psychometric properties for use of rating of symptoms in bipolar I patients at routine visits, but there is also room for improvement.


Methodology Review: Assessing Unidimensionality of Tests and ltenls
Various methods for determining unidimensionality are reviewed and the rationale of these methods is as sessed. Indices based on answer patterns, reliability, components and factor analysis, and
MOKKEN Scale: A Pascal Program for Nonparametric Stochastic Scaling
A nonparametric Mokken scale analysis (a stochastic elaboration of the deterministic Guttman scale) and program is described, and it is usable on many microcomputers and larger systems.
Quite often when we analyze attitudinal data with log-linear methods, we run into difficulty with groups who are predicted to be toward one extreme or the other of an attitude dimension. Formally,
A New Model for Scaling Response Patterns: An Application of the Quasi-Independence Concept
This model, using methods already developed for the study of quasi-independence in contingency tables, is shown how to test whether the model fits the observed data, estimate the proportion of intrinsically scalable (and unscalable) individuals, and estimate the distribution of the intrinsically scalable individuals among the d different scale types.
A Nonparametric Approach to the Analysis of Dichotomous Item Responses
An item response theory is discussed which is based on purely ordinal assumptions about the probabilities that people respond positively to items. It is considered as a natural generalization of both
Linear Versus Models in Item Response Theory
A broad framework for examining the class of unidimensional and multidimensional models for item responses is provided by nonlinear factor analysis, with a classification of models as strictly
The Construction of a Developmental Scale for Seriation
In this study the relationship between seriation tasks and number line comprehension tasks are reported. Subjects were 595 children from kindergarten and primary school grades 1 and 2. Three types of
Contributions to factor analysis of dichotomous variables
A new method is proposed for the factor analysis of dichotomous variables. Similar to the method of Christoffersson this uses information from the first and second order proportions to fit a multiple
MOKKEN Test for the Robustness of Nonparametric Stochastic MOKKEN Scales
A description of a Mokken test program to test the robustness of nonparametric stochastic scales is presented. For each sample and the whole population, different scale statistics, both on scale and
